The Battle of Mechanicsville, Virginia was a battle of the American Civil War that occurred on June the 26th, 1862, during McClellan's attempted approach to Richmond. Robert E Lee crossed the Chickahominy with 35,000 Confederates, intending to join Jackson's 25,000 troops and demolish Porter's command of 20,000 of McClellan's troops and cut off the latter's communications with his base. Jackson was for once late in arriving, and Richmond was for a time in considerable danger. A P Hill's division advanced first and encountered at Mechanicsville a small-force of Confederates, who were dispersed. Just beyond the town McCall. was drawn up with a strong force on Beaver Dam Creek. The Confederates attempted to turn McCall's flanks, but were repulsed with great loss each time.
